-- For the same amount of radiated RF power, AM transmitters use more primary
(utility) power, because the modulation must be applied to the final output stage,
requiring high audio power.
-- Commercial FM stations will typically radiate more RF power than AM stations,
because of the relatively higher free space attenuation at the higher frequency of
the commercial FM band ... they need more power to cover the same size 'market'
area. But that's the result of their spot on the radio dial, not their modulation technique.

What is the energy of a radio station that broadcasts at 1120 kilohertz on the Am?
The frequency on the radio dial doesn't tell us the power the station is using to transmit. There may be an AM radio station at any spot on the dial that is transmitting at any power level between, maybe, 10 watts and 50,000 watts. That decision is made when the radio station applies for its license, and the license to operate is granted.

If there is no power getting to your 94 VW Jetta radio how do you fix it?
Check the fuse in the fuse panel. Also look and see if there is an inline fuse blown. I already checked the fuse panel and the fuse on the back of the radio. I don't know what the problem could be. The radio is not burnt because I replaced it and still no power. There may be another inline fuse somewhere between the fuse panel and the radio. Do you have power at the radio? I assume you do not. I would check, with a multimeter, where the radio power cable is connected at the fuse panel and see if you actually have power. If you do then you know that somewhere between that point and the radio you have a problem. As a last resort you could just run a new power cable to the radio from the fuse panel. Be sure to install an inline fuse if you do this. How do I run a new power cable to the radio from the fuse panel and install an in-line fuse?
